Fish need more than plants and caves to feel at home. One way to provide protection is to use a suitable background, which indicates a safe zone in the aquarium. A background is not only welcome for the fish but it is also helpful for hiding unattractive technical items. Give your aquarium more flair and offer your aquarium dwellers a species-appropriate environment.
Cut the foil background all around one cm smaller than the aquarium or terrarium background. Lay the aquarium/terrarium with the front pane on a stable enough surface. Apply an external cap of JBL Fixol on about the middle of the back glass. Lay pre-cut foil background on top and smooth it with the enclosed spatula from the centre outwards, avoiding bubbles. Wipe off excessive glue with a cloth or tissue paper. Fix background foil all around with transparent adhesive tape. Can be removed with clear water at any time.
